ing arms i', the arrangement being-such that the proper operation of the clamping mechanism forces the clamping gage or wall 116 bodilytoward the fixed gage orwall l to apply endwise pressure on the casting or molding elem-ents, not sliown,-for use upon the casting car, which casting er molding` elements form no part of this invention and hence are not described or shown in full lines. To insure the operation of the clamping mechanism, hooks 2l are pivoted upon p the wear plates 5 for engagement with the outeredges rof the angle brackets 19 to form t resistance points to the force exerted in the clamping operation, upon the gage or wall '-lhe ends of certain of the cross timbers lelfatkthe opposite sides ofthe bottom from {gagerail ll, are notched in their upper sides for the accommodation of wear platesA corresponding to wear plates 5, and bolts kused to secure the wear plates to the said `vtimbers la, are also employed for fastening imderlying` brackets in place corresponding to brackets G.

A movable side wall or gage 23 overlies lthebottom 15, and is equipped with socketed brackets 24 for engagement by clamping screws Q5, mounted 1n angle brackets 26 pivotally` mounted on the plates corresponding y to plate G, and hooks 27 mounted onthe plates corresponding rto wear plates 5, en-

i gage brackets QG to perform the same function for gage or wall 23 as that performed by brackets l) for gage or. wall 16, .during the clamping operation, the gage or wall 23 applying Sidewise clamping pressure on the casting or molding forms hcreinabovermentioned. n I

As another and perhaps more satisfactory means for clamping the movable gages or walls in place, l-may mount cam levers Q8.

in the pivoted brackets at trie sides and ends of thebody, so that the operation of said cam levers shall. applythe clamping pressure, and to holdthe cam levers against vrowadjaceut thereto, same ligure, to relax the clamping pressure.

rlhe gages orfwalls are preferably provided with internal cleats 60, which areadapted to overlie grooved f lmarginal portions of the form members (see dotted lines Figure 3) to guard against such members working upwardly when subjected tothe pressure of the-.movable gages or walls.

`that of the said walls rside wall, and re,

recesso lVlien the forms are placed within this body, the clamping devices are swung upward into enoagement with the respective socket plates, and the hooks engaged with the pivoted brackets. rllhe clamping elements are then operated to clamp the form members together. After the casting or molding operation completed and the ccmentitious units are set, the hooks are knocked loose to permit the clamping elements to be withdrawn and the clamping gages or walls removed preliminary to the dismantling of the form for the removal thereof and of the molded units.

From the above description, it will be apparent that I have produced a constructionI in which play is provided. or accommodated between the gages or walls` and the bot-tom of the body, which it has been demonstrated,

therefore susceptible of long and continuous service in the production of perfectly uniform and interchangeable concrete units or blocks, and while I have shown and `described the preferred construction of the apparatus, it is to be understood thatthe right is reserved to make' such changes as properly fall within the'spiritvand scope of thev appended claims.
